The Lowdown
Alright, this is Rusty. Let’s break it down for Karramarro. To be honest, the next week and a half is looking pretty flat and frustrating. There's a long stretch of tiny, weak swell and mostly messy wind, so don’t get your hopes up until the very end of the month. The water is sitting at a warm 76.6°—that’s much warmer than usual for this time of year, which is a bit of a curveball.
The first real glimmer of something shows up on the morning of Thursday, August 20th. We’ve got a weak 3.0ft NW swell creeping in with an 11-second period. The combined swell energy is still weak (213), but the morning turns glassy. It’s surfable, but “ordinary” is the word—don’t expect any gems.
We drift through a whole stretch of days after that with nothing worth paddling for. Friday the 21st sees the swell bumping up to 4.9ft from the NW, but it’s cross-on wind and the energy climbs to a moderate 442—still, the quality is marginal, and the conditions are just not clean for a good session. The whole second week, from the 22nd through to the 29th, is mostly small, weak, and poorly aligned. A rare clean offshore breeze on Monday the 24th morning is wasted on a tiny 1.6ft swell.
Then, hold onto your board—Sunday, August 30th morning is the only true standout in this whole forecast. The swell punches up to 5.2ft from the NW, with a long 12-second period and the combined energy ramping up to a solid 711. That’s the most power we see here. And the wind? Dead flat glass. It’ll be clean, lined up, and making the most of that point break setup. This is for the advanced crew—5.2ft with that energy on a point can be a proper session.
Monday the 31st morning is a decent hangover: 4.6ft NW swell, 11-second period, glassy again, with energy at 431. Good conditions, but not quite the standout that Sunday is.
Overall, wait it out. August 30th is your date.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
